8.2-759: Wireless didn't come up

[joe]

Observed in two laptops. After 759 was installed (olpc-update) and the laptop was rebooted, it came up with dark network lights. Then, rebooting the machine fixed the problem.

Kim, Chris and Wad witnessed the event. The log file is attached.

Joe, I only saw this on one laptop. We don't know whether the loss of wireless on the other laptop was at boot or a crash after boot, because that laptop was rebooted before logs were taken.

I saw something similar, with 8.2-759 on my G1G1 XO. Both left-hand WiFi LEDs were dark mostly, only rarely flashing. Very unfamiliar behaviour. Can't remember any other details, but will watch for it from now on. Is it a bug or a feature? Maybe to save power?

I believe the "install default" for 759 is "allow suspend". When I failed to pay attention immediately upon rebooting (after the olpc-update), the XO suspended (and was hard to wake up). Note that suspend *will* turn off the left LEDs.

Replying to mikus:

I believe the "install default" for 759 is "allow suspend".

It allows suspend on power button press or lid close (as every build we've made in the last year or so does) and doesn't automatically idle-suspend.

Do we know of any plausible reasons the network lights might have been dark other than suspend? Can the issue be reproduced? Do the logs contain any useful data?

The logs tell us that the wireless device didn't enumerate on the USB bus at boot. This is a plausible reason for the network lights being dark.
